GoogleSignInOptionsDEFAULT_SIGN_IN

Default configuration for Google Sign In. You can get a stable user ID and basic
profile info back via
getId() after you trigger sign in from either
silentSignIn(GoogleApiClient) or
getSignInIntent(GoogleApiClient). If you require more information for the
sign in result, please build a configuration via new
GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)}.
